AIM: To determine the predictive value of the 2 week post-selective laser trabeculoplasty (SLT) intraocular pressure (IOP) by comparing it to the 4 week and 3 month values. METHODS: A retrospective chart review of eyes that underwent SLT between 2001 and 2004 was performed. The primary outcome measure was IOP. Demographic and medical data were collected for correlational analysis. RESULTS: 132 eyes of 95 patients were identified, none was excluded. Of the eyes that exhibited a decrease in IOP of > 1 mmHg at 2 weeks postoperatively, 99.24% continued to show a lowered IOP at the 4 week and 3 month visits. For these patients, the Pearson's r value between 2 weeks and 4 weeks was 0.708 (p value = 0.01) while the r value between 2 weeks and 3 months was 0.513 (p value = 0.01). CONCLUSIONS: The 2 week visit post-SLT predicted the 4 week and 3 month visits if the 2 week visit demonstrated a decrease in IOP. These findings suggest that those patients who had a decreased IOP at 2 weeks and are at their goal IOP may not need to be screened until 3 months postoperatively.
